FINAL YEAR PROJECT PROPOSAL ELECTRICAL ENGINEERING

HASALA DHARMAWARDENA
ELECTRICAL ENGINEERING
LEVEL 3

DRAFT PROPOSAL FOR FINAL YEAR PROJECT 09/10
DESIGN OF A GENERAL PURPOSE DISTRIBUTED INDUSTRIAL AUTOMATION SYSTEM


PROPOSAL
DISTRIBUTED INDUSTRIAL AUTOMATION SYSTEM

OBJECTIVE

The objective is to create a distributed automation system bypassing the need for a dedicated specialized controller like a PLC.
The idea is to find and quantify the specific requirements where such a system can be implemented instead of specialized controllers.
It is observed that for some instances of control and data acquisition, the need for specialized controllers doesn’t exist, but due to bad engineering they are deployed.
The project proposes to create a system from ground up with respect to software as well as hardware.
To find the inherent weaknesses attached with this concept and to find the solutions to them.


COMPONENTS ANALYSIS


1. Serial to RS485 converter module.
2. Digital Input modules
3. Digital output modules
4. Analog input ( 0-10V/ 4-20mA) module
5. Analog output ( 0-10V/ 4-20mA) module
6. Software to interact with the serial port and its user friendly API to simplify control algorithm programming and execution in the PC.


EXTENSIONS


1. Implement modbus protocol at the application layer so as to make the system be compatible with the industry standard.
2. Develop modules for widely used Inputs and Outputs
• Thermocouple (k/j type) inputs
• Load cell inputs

3. Develop suitable software to configure these proposed modules.
4. To develop a user friendly, intuitive front end GUI to seamlessly integrate control algorithm development and HMI development.





PROPOSED RESEARCH AREAS

1. Ways to optimize the communication speed of a distributed system
2. Analyze how EMI affect the system. Propose and implement solutions to overcome them.
3. Find the most suitable operating system (general purpose) to handle real time I/O as relevant to industrial automation.
4. Quantitatively analyze the speeds that can be achieved. Research how the performance of the system varies with factors such as number of daisy chained modules and installed IO capacity. Try to formulate simple formulae to connect all these factors and derive the maximum latency.




CONCLUSION

Given the importance of automation in industrial processes, the project will give us a practical insight into the heart of Industrial automation.

TECHNICAL GUIDELINE FOR SUCCESSFUL IMPLEMENTATION OF NET METERING

IEEE STUDENT BRANCH
UNIVERSITY OF MORATUWA
PROPOSAL FOR DRAFTING TECHNICAL PAPER
TECHNICAL GUIDELINE FOR SUCCESSFUL IMPLEMENTATION OF NET METERING


PROPOSAL
TECHNICAL GUIDE: NET METERING
OBJECTIVES
• To serve as a comprehensive guide to all parties concerned.
• To analyze in depth the economic aspects and forecast for the future
• To analyze in depth the technical aspects and forecast future
• To analyze the social environment aspects and forecast for the future
• To serve as a guide to the consumers to choose the optimum installation capacity as well as the optimum energy source mix.
• To analyze the practical problems faced by users as well as the suppliers and to propose suitable measures to overcome them.
• To compare the prevalent systems with the net metering system
• To propose a suitable framework to be implemented island wide to make distributed generation a reality.
1. ECONOMIC ANALYSIS
PREVALENT RENEWABLE ENEGY SOURCES AND THEIR ECONOMICS WITH RESPECT TO OUR COUNTRY
1. Wind Turbines
2. Solar –PV
3. Mini hydro
4. Integrated solutions E.g. Wind and Solar
PROPOSED NETMETERING SOLUTION AND THEIR ECONOMICS WITH RESPECT TO OUR COUNTRY
1. Wind Turbines
2. Solar –PV
3. Mini hydro
4. Integrated solutions E.g. Wind and Solar
THE ANALYSIS
It will include all aspects such as energy source installation, coupling devices (meters/inverters/isolators) required maintenance over the lifetime of the installation.
All economics will be analyzed using rough approximation Eg: Simple discount method
A COMPARISON BETWEEN THE VARIOUS OPTIONS AVAILABLE
To give the users an idea about what sources are most suitable for energy generation

2. THE ASSUMED OUTCOMES
Here the analysis is done with respect to a national and global framework and will try to analyze the system at a much broader platform with a scope encompassing environment, non renewable energy dependence. Etc…
3. TECHNOLOGY SPECIFIC PROBLEMS AND SOLUTIONS TO OVERCOME THEM
1. To generate simple formulae that gives the ability to calculate optimum installation capacity for each source as well as hybrid sources.
2. Connection diagrams, specific components required and the modifications required in the users installation.
4. ECONOMIC ASPECTS WITH RESPECT TO DIFFERENT CONSUMER GROUPS
1. Domestic users
• Low end <300Kwh
• High end >300Kwh

2. Agriculcural users
3. Industrial users
The analysis of economic effects with respect to the prevalent tariff structure of Srilanka.

5.THE MARKET
Here the research will try to find the available brands in the market as well as their quality and reliability. The information will be presented for the eyes of the laymen.

A tribute to the pioneers of the Gavel club of the university of moratuwa

Dear Gavelians,

Today is indeed a very sad day for me because the pioneers of the gavel movement
are leaving the club for greater heights. From today onwards the club will be
represented by 2nd generation gavelians.

I can still clearly remember my first meeting where the 1st president of the
club Tharaka aiyya presided.

The way the club has developed into a mature and rooted club in such a short
time is unbeleivable.

Unlike other clubs the exponential growth of the Movement is completely due to
the dedicated work carried out by the pioneers who are now leaving the club.
They were extremely talented and hard working and each one of them inspired us,
their juniors in innumerable ways.

Dulini Akka was the live wire of the club from the very beggining and her hard
work was one of the major factors of the clubs' success.

Apart from being a truly talented toastmaster the way she worked with people was
a great example for all of us. Thank you akka for everything, u will always b
revered in the club as the live wire which gave life to the university gavel
Movement.

Dilini akka was a great manager managing everything and presided over a golden
age of the club. The trademark of her leadership was the extremely smooth
functioning of the club. Apart from that she was always their to encourage us
whenever we were downcast and defeated. Thank you akka for everything.

The gavel club truly prospered not just because of the leaders but because of
the unbelievably talented pioneering gavelians of the club. Nuwanpriya aiyya was
a model toastmaster with unsurpassed skill and was a kind mentor for all of us.
Aravinda aiyya was a great inspiration to all of us due to his style of speaking
which was truly unconventional but surprisingly effective.

Apart from them, the different styles and awesome personalities of Nilendra aiyya,Radeeshan
aiyya,Lakshitha aiyya, Bodul aiyya, Chamath aiyya, Aravinda(sara) aiyya,hiranya
aiyya contributed to making the gavel club the top gavel club of the country.

All were truly amazing gavelians and having such a set of top class
personalities in the club was a remarkable thing in itself. Indeed they were all
successful in their careers as well, and topped every one in their respective
fields.

The standard set by them in the club is world class and even maintaining that
sort of class and professionalism will definitely be a very very difficult task
for us.

But we do hope to work harder and strive to increase the standard of the club.
We really do appreciate the great services rendered by you all to the club by
creating this club. (which will help all the undergrads develop their soft
skills in the years to come)

We cherished every moment we spent with you and will never forget the great
moments we shared together.
Once again thank you for the great treat given to us and the quality time you
spent with us today .

May all your dreams come true!
